But the trend has since changed due to better warning labels, education of prescribers, changes in iron preparations, and consumer awareness.
Answer: Principle of Original Horizontality.
According to the principle of original horizontality all rock layers are horizontal in nature and this is specific to sedimentary rocks. The younger sediments remains in the top layers and older ones remains at the bottom. These sediments accumulate in horizontal and parallel layers and becomes compact to form rocks in the end.
Valence electrons would be found in the outermost shell of atom models!
Hope this helps (:
